Graph f(x)= square root x-3 please show me how you get the answer. Please help trying to help my grandson and I don’t understand. Thirty points.

Answer:
picture down below hopefully this helps<3
Step-by-step explanation:
Answer: plot the following:
(3,0)
(4,1)
(7,2)
(12,3)
Step-by-step explanation:
X = 3. y = sqrt (3-3) =0. (3,0)
X = 4. y = sqrt(4-3 ) = 1. (4,1)
X = 7. y = sqrt(7-3) = 2. (7,2)
X. = 12. y = sqrt (12-3) = 3. (12,3)
